Abstract

In a video signal processing system apparatus for differentiating between video field types includes circuitry (18,20) for measuring an interval between a vertical signal component 30-34) and a predetermined transition of a horizontal signal component (12-16). Measured values from successive fields are compared (22-28) to provide a signal related to the respective field type, e.g., odd/even.
